Název v původním jazyce

Extraradical mycelium of arbuscular mycorrhizal fungi radiating from large plants depresses the growth of nearby seedlings in a nutrient deficient substrate

Popis výsledku v původním jazyce

Tripleurospermum inodorum was cultivated either non-mycorrhizal or inoculated with arbuscular mycorrhiza (AM) fungi in the central compartment of rhizoboxes. After two months, seedlings of T. inodorum or Sisymbrium loeselii were planted in lateral compartments, colonised by the extraradical mycelium (ERM) of the pre-cultivated T. inodorum in the inoculated treatments. Two AM fungal isolates and two substrates: spoil bank soil and soil-sand mixture were compared. In the nutrient-poor substrates, the pre-cultivated T. inodorum responded positively to mycorrhiza; more pronounced in P than in N uptake and growth. In contrast, the growth of both, the host and the non-host seedlings, was inhibited in the mycorrhizal treatments. The growth inhibition was attributed to N depletion in the lateral compartments by the ERM radiating from the central compartment. The results point to an importance of mycorrhiza in the coexistence of large plants and seedlings in nutrient deficient substrates.
